JOHN J. scHILLmGER, on NEW YORK, N. Y.

- FIRE-PROOF BUILDING.

SPECIFICATION formingpart of Letters Patent No. 293,523, dated February 12, 1884.

Application filed October 10,1883. (No model.)

' To wZZ whom it may concern:

and protecting the lower, edges and the sides of the floor-beams and the under side of the flooring.

To this end the invention consists, essentially, of a fire-proof sheathing molded in sections,

, and each section in a single piece, and of such shape that it extends across the lower edge of the beam and vertically along the sides thereof, and horizontally along the flooring.

The invention also consists in a fireproof sheathing for the floor-beams and floors of buildings, molded in sections to the general shape of the lower exposed portions of such beams and floors, and with a depression in the top of the floor-sections, to relieve the same from downward pressure.

The invention is fully illustrated in the accompanying drawings, in which Figure 1 is a cross-sectionof a portion of a floor with its beams containing my invention. Fig. 2 is a plan view, omitting the floor. Fig. 3 is an in verted plan view.

Similar letters indicate corresponding parts.

The letterA designates the floor-beams, and B the floor, laid on the beams in any usual or suitable manner.

C denotes the sections of the fire-proof sheathing. These sections are molded in any usual or suitable inannerto the general shape or outline of those portions of the beams and floor which are exposed in a lower directionthat is, each section is molded-in one piece, of such shape that it will extend across the lower edge and vertically along each side of the ing can be divided from each other in various ways,and a detailed description thereof is therefore deemedunnecessary.

The letter D indicates the depression in the top of the floor-sections of the sheathing. This depression extends nearly the whole width of the proper sections, and by its means the sections are relieved from downward pressure, due to the sagging of the floor from natural causes, or by a heavy weight thereon. Another effect of the depression D is to cause the floorsections to fit snugly, inasmuch as they come in contact with the floor only at the edges.

For the purpose of supporting the sections 0 in the required positions, they are attached to the beams or floor, orboth, by nails, screws, or other similar fastenings, which may be located in the joints between the sections or in the body thereof, and when the sections have been fastened the joints are preferably filled up by a suitable cement.

I am aware that it is not new to protect the proof material, and such, therefore, I do not broadly claim; but

What I claim as new, and desire to secure by Letters Patent, is l. A fire-proof sheathing for the beams and floors of buildings, molded in sections, and each section in a single piece to extend across the lower edge and vertically along each side of the floor-beam, and laterally or horizon tally along the floor, substantially as described. 2. A fire-proof sheathing for the floor-beams and thefioors of buildings, molded in sections to the general shape of the lower exposed portions of such beams and floors, and with a depression in the top of the floor-sections, to re lieve the same from downward pressure, substantially as described. I

3. The combination, with the floor-beams and floor of a building, of a fire-proof sheathing molded in sections, each section being in a single piece and extending across the lower edge and vertically along the sides of the floorbeam, and laterally or horizontally along the floor, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN J. SCHILLINGER.
